1. a violent disturbance. Mayhem, may result in people getting injured, maybe even killed. Property damage and destruction, arson and vandalism usually occur during a riot.

2. a trip, a blast, a gas, anything that is funny and/or cracks people up. Something that is fun.

1. In the spring of 1992 many people believed that the "Rodney King riots" that erupted in several Americancities was a case of "black rage". I saw on ABC-TV live coverage reports that the rioters had plenty of non-black people in their ranks: there were a lot of white and Hispanic looters and vandals as well. Also, one morning that week, ABC showed that some black-owned shops and businesses had also been trashed during the disturbances. The weeklong ruckus was not a "racial" thing. It was for most of the participants an excuse to chuck a brick into a pharmacy window, or to steal a stereo from an electronics store, or simply just to "fuck some shit up".

2. I was driving in Canada when I heard that Phil Hartman was murdered by his wife, who then killed herself. Still, to this day nobody knows why it happened. It'll probably forever be a mystery. Nonetheless, it was a tragic event. I've seen Phil on SNL and other TV shows and movies, and he was a total riot.
